Fan Casting Vivian Alvarez / The Overseer in The Overseer

Sasha Calle as Vivian Alvarez / The Overseer: A long-forgotten superhuman who comes out of retirement to save New York City from devastation after learning about the true nature of her neighbor's father. Her titular alias is named after director M. Night Shyamalan's Unbreakable character David Dunn, played by Bruce Willis, who took on the same name as a crimefighter in those films. Calle also portrays Sierra Alvarez / The Banshee, Vivian's twin sister and arch nemesis, while Rachel Zegler physically plays that role on-set.
